cl_survey command

Edit online

Purpose

The cl_survey command analyzes the asynchronous Geographical Logical Volume Manager (GLVM) configuration. It collects statistical information about cluster configuration, analyzes the collected data, and suggests configuration updates if any.

Syntax


/usr/es/sbin/cluster/utilities/cl_survey -t <total time> -i <interval>

Description

To run the cl_survey command, specify the total runtime and the interval time for data collection. The cl_survey command creates a report that indicates disk usage at the end of total run time. The command temporarily logs the disk statistics in the diskstat.log file and logs the network statistics in the netstats.log file. The cl_survey command records the remote physical volume (RPV) statistics of a volume group and logs the RPV statistics into the statsinfo.log file.

Options

-t <total_time>
Total runtime in seconds for which the cl_survey command runs and collects the data. The valid value is in the range 60 - 31536000 seconds.
-i <interval>
The interval time in seconds between two consecutive data collection period. The valid value is in the range 2 - 3600 seconds.
-h [--help]
Displays help information.

Output file

/var/hacmp/log/clsurvey/Clsurvey_Run_Analysis_information

Example:
To analyze the cache and bandwidth usage of an asynchronous volume group for 1 hour with 2-seconds interval time, run the following command:
/usr/es/sbin/cluster/utilities/cl_survey -t 3600 -i 2
The output is logged in the var/hacmp/log/clsurvey/Clsurvey_Run_Analysis_information file. All the associated log files are moved to the /var/hacmp/log/clsurvey/data directory.
